Abstract
A grating made in the core of an optical fiber presents a nonuniform and asymmetrical profile of the modulation of the refractive index in the direction of the length, which profile is represented by a curve that rises gradually and monotonically from a minimum and substantially null value, with substantially horizontal tangent, in correspondence with an end of the grating to a maximum value, also with substantially horizontal tangent, which is reached in correspondence with the other end of the grating.
